Shin, I did track the car, but this summer I was off with my school's Formula SAE team helping get the car, that I spent all year helping construct, to become one of the world's best. That left me penniless for racing my own car. Next season is looking slightly better if I don't go to Europe with them.
I KNOW that the changes I've made will minimally affect any downforce or drag made by it, but it will still change the airflow. I've seen what huge changes made to the diffuser on our formula car only make minute tenths of a percent changes in downforce and drag. Whereas not having the diffuser altogether cause sthe drag and downforce to both reduced by 15-20% and 60-70%. And this is on a 330 pound car that has a 0-60 of less than 4 seconds.
Our RX-8's, like most cars, are kind of wedge shaped with the pointy end first. At lower speeds, this causes a bit of downforce. However at high speeds the car will act like a wing, create some lift and give you that floaty feeling. The air traveling over the top is at a lower pressure than the bottom because it must travel faster. (Try it yourself with a small strip of paper. Hold one end at your bottom lip so you can blow over it. Blow and you'll see the strip of paper rise because the faster moving air is at a lower pressure.)
I can see how what I've done, coupled with the pipey exhaust, could cause some more turbulence since there are not any venturis or even a flat undertray. But, giving the same amount of air more area to occupy and escape cannot create lift if its on the high pressure side. Air cannot curl under, this is because both sides curl towards the dead area right behind the trunk and that the air coming off the top is at a lower pressure than the bottom.
Lol. And no, I didn't get hit with an egg.

Momentum Keeps Me Going
...if you want to look like a rolling accident 
and too broke to repair... hey whatever...you think it's 'in'....but IMHO it reflect poorly on the RX-8 community ... similar to slammed fart can ricers....just worse if that's possible.
